EYEGLASSES.

Specification of Letters Patent.

Patented Aug. 6, 1907.

Application and February 17,1906. serial No- 501,560.

To all whom it may concern:

Be it known that I, LEO F. ADT, of Albany, in the county ol Albany and State of New York, have invented certain new and useful Improvements in Eyeglasses; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reterencenumcrals marked thereon.

I My present invention relates to eyeglass mountings and particularly tothat class in which the lenses are conn ceted by a relatively rigid bridge and the guards or portions bearing upon the wearers nose are pivoted upon the mounting and provided with forwardly-projectingfinger pieces by means of which the guards niay be separated and otherwise-manipulated, while the gripping or holding action is performed by a spring or springs operating'upon these guards to bring them to gether."

The invention consists incertain improvements and. combinations of parts whereby not only is the construc tion simplified and the operation of the parts rendered easier, but each of the guards embodies in itself all of the parts necessary for causing the various operations required, and the m cans for securing it in position upon the mounting or support, and in the preferred form they are each constructed of a single piece of sheet metal.

The invention further consists of certain constructions and combinations of parts all as will be hereinafter more fully explained, the novel features being pointed out in the claims at the end of the specification.

In the accompanying drawings: Figure l is a front ele 'ntion of a pair of eyeglasses constructed in accordance with my invention. Fig. 2 is a top plan view of the same. Fig. 3 is a bottom plan view. Fig. 4 is a similar view with the guards separated. Fig. 5 is a vertical cross sectional view taken through the center of the bridge, and Fig. 6 is a perspective view of one 7 end of the bridge with the guard removed. Fig. 7 is a detail perspective view of the guard. Fig. 8 is a sectional view on the line y-y of Fig. 1 showing the outer side of the operating end oi the guard. Fig. 9 is a perspective view showing themanner oi disengaging the guards from the mounting.

Similar reference numerals in the several cate similar parts.

In mountings of this general description the lenses indicated by 1 are connected by a relatively rigid arched bridge, and in the present construction the bridge is directly connected to the lenses; 2 indicating the central arched portion extending over the wearers nose and adapted to contact therewith if desired, and at the ends are providcdthc attaching lugs S'extending over opposite faces of the lonsesa 1d connected by the usual screw 4, said ends also beinxpvldcd with the vcrti(rally-extending edge-bearing lugs 5. At the ends figures indiof the arched portion, and betwe n it and the lenses are provided the horizontally-extendin g surfaces constituting supports upon which the guards are adapted to rest, andt'rorn these extend the vertical pivot pins 6 having heads '7. Arranged beneath the ends of the bridge and preferably at the rear side of the mounting is a holding projection or lug 8 with which a portion of the guard cooperates in the manner hereinafter de scribed.

As stated, while I prefer to make the bridge and lensattaching part in a single structure as shown, they can be formed separately and connected, but either, if

, made separately and connected, may constitute a support upon which the operating parts oi the device are mounted.

The part which I term the guard embodies a body portion or arm pivotally mounted upon the pin 6 on the support and extending transversely of the plane of, the lenses, having upon its rear portion a bearing pad or pad adapted to rest upon the nose of the wearer,

and in the present instance consisting of a lower loop 9 and the upper bearing pad 10 connected to the loop and of such nature that it will be relatively more resilient.

11 indicates'the operating arm of the guard extending forwardly from the pivot for a short distance, and.

thence extendin rearwardl a ain beneath the so D 3 'port,lorm1ng a resilient or spring arm 12, the edge of which bears against the mounting, preferably above the lug 8, and having a sliding connection with the same, the tendency of said'arm being to force the operating ends of the guards outward and the bearing pads of the guards toward each other. The end of this arm 12 is slightly curved in the direction of its movement about the pivot so that the yielding pressure exerted upon the bearing pads will be nearly unilorln at substantially all portions of its movement, thereby enabling the bearing pads to be readily opened to their widest extent without unduly increasing the tension. This feature of providing a separate and positive pivotal bearing for the guards and constructing the latter with spring arms having a sliding bearing upon the mounting, insures the positive and uniform movements of the guards, and also facilitates the construction in that the guards as a whole may be each made of a single piece of spring metal, and

as will be describe .l, may be locked in engagement A detachable connection between the guard and the pivot pin on the support is provided by making an open slot 16 in the inner edge of the guard which engages said pivot pin below its head, the material of the guard between the outer end of the slot and the lens edge-bearing lugs being wide enough so that the guard cannot be slid far enough outward to become disengaged from the head of the pin, under ordinary circumstances, and the tendency of the spring arm 12 being to move the guard as a whole so that. the pin will occupy the bottom of the slot.

The guard may be readily detached, ii desired, by disengaging the end of the spring arm 12 from the lug 8, moving it downwardly and iorwardlybeyond the edge of the lens, and then by tilting the guard vertically, as shown in Fig. 8.

The amount of separation of the nose-bearing pads may be limited by suitable stops, but I prefer to cause shoulders 17 on the guards to come into contact with the lens edge-bearing lugs for this purpose, as shown in Fig. 2.

The guards as a whole may be removed in the manner described and replaced by the reverse movement, thus enabling guards having different bearing-pads to be substituted if desired, orpermitling a replacement of the guard, if one should be broken or otherwise injured. It will be noted that the guards embody not only the nose-bearing pad and the operating arm, but also the actuating spring and the meansfor holding them in locked engagement with the support or mounting, so that no screws. separate springs or other small parts. are required, and us in the preferred cons1 ruction the whole of the uard is of a sin lo niece of. sheet metal, which may be stamped .irom a flat blank and then bent up as shown. the construction is much simplified and cheapencd.

Of course other forms of pads bearin upon the wearers nose may be provided, if desired, but I find the one shown to be eificient, as the arm bearing the pad l0 will not onlyhave a spring action, but may be adjusted to bear with greater or less pressure on the nose.

There are no parts liable to get out of adjustment or become loose and the mountings once assembled. will be capable of operation indefinitely without adjustment.
